interactive whiteboard vs touch screen

Almost all current smart projections use DLP seamless splicing screen projection technology, so how much do you know about this technology? Today I will briefly analyze the working principle and characteristics of this technology. The light source hits the light on the lens to obtain usable parallel light. The parallel light passes through the color wheel to obtain a uniform rectangular spot, which is then processed by DMD, the core component of DLP seamless splicing screen projection technology. Finally, the light is hit on the projection lens and passed The lens gets the projection we need, which is the working principle of DLP seamless splicing screen projection technology. DLP seamless splicing screen display board has extremely fast response time, you can switch independent pixels many times when displaying a frame of image. In addition, the strong reflective surface of the DMD chip can eliminate the obstacles in the light path and allow more light to be projected on the screen, and maximize the use of the projector’s light source to obtain a higher contrast picture. These are DLP seamless splicing screen projections. Advantages of technology. In addition, in terms of size, the DLP seamless splicing screen chip is lighter and smaller, which is one of the reasons why DLP seamless splicing screen projection technology is widely selected for small-size products such as smart projection. In addition, at the end of last year, Texas Instruments also launched a smaller size 1080P chip for smart projection. The compression of the chip size

LCD splicing screens are divided into optical seamless LCD splicing screens and electronic seamless LCD splicing screens. The realization principle of the optical seamless LCD splicing screen is to install a special optical glass panel body on an ordinary 3.5mm panel, and realize the principle of line-of-sight refraction through the glass, so that the originally split screen can be seen in an image through the optical glass , The seams with black edges are completely invisible, and the display effect of the picture is real. The realization principle of seamless LCD splicing screen electronics is that by installing a special electronic bar on each panel unit, the electronic bar emits light equivalent to LED, and the light is emitted by two electronic bars between the seams, which can be displayed on the display. Achieve seamless seams. The seamless LCD panel joining technology has reached an unprecedented level, realizing the arrival of the era of true seamless joining technology. The seamless LCD panel joining technology is used in the high-end display field. It can be said that the visual impact it brings is also unprecedented. The seam adopts full-screen active LED electronic pixel compensation display, and the optical lens and optical refraction principle are seamless. The pixel pitch of LED electronic pixel correction is 1.5mm or less. The electronic pixel compensation LED adopts SMD label technology and does not use large particle lamp-like display. After LED electronic pixel correction, the edge of the condenser lens with high transmittance is added to

Digital signage has been developed for many years, but due to various objective reasons, it has not yet been popularized on a large scale. However, in some government service establishments and high-end commercial establishments, digital signage has been widely adopted. This shows that digital signage Signage is moving forward along the logical route of commercial development, and it has not stopped, let alone its development. Based on years of experience in digital signage projects, we believe that the following three changes are initially expected in digital signage in the next three to five years: Development trend 1, response methods will be more diversified As far as the interactive mode of digital signage is concerned, the response mode is relatively simple. Basically, it is operated by the touch screen. After clicking, the digital signage will make corresponding actions according to relevant instructions, such as issuing tickets and so on. However, people’s pursuit is endless, and more needs have not been met for the time being. At this time, new solutions are often needed to solve these pain points. Therefore, will there be new ways to respond in the future? , The answer is yes, such as voice interaction, voice interaction, and interconnection with mobile phones, etc., may be the specific form of future response methods. Development trend 2, the full integration of reality and virtual We are no longer unfamiliar with the terms augmented reality (AR) and virtual reality (VR), because over the years, the development of AR and VR has
